QjackCtl is a simple Qt application to control the JACK sound server daemon, specific for the Linux Audio Desktop infrastructure.

Written in C++ around the Qt framework for X11, most exclusively using Qt Designer.

Provides a simple GUI dialog for setting several JACK daemon parameters, which are properly saved between sessions, and a way control of the status of the audio server daemon. With time, this primordial interface has become richer by including a enhanced patchbay and connection control features. Last changelog:

0.4.5 2017-04-27 Pre-LAC2017 release frenzy. 10 months ago

- On some desktop-shells, the system tray icon blinking on
XRUN ocurrences, have been found responsible to excessive
CPU usage, an "eye-candy" effect which is now optional as
far as Setup/Display/Blink server mode indicator goes.

- Added French man page (by Olivier Humbert, thanks).

- Make builds reproducible byte for byte, by getting rid of
the configure build date and time stamps.
